Patented Jan. 5, 1909.

Application filed April 1'7, 1906, Serial No. 312,206. Renewed May 29,1908. Serial No. 435,693.

To all whom it may concern:

Be it known that I, LACEY Y. WILLIAMS, a citizen of the United States,residing at T0- ledo, in the county of Lucas and State of Ohio, haveinvented new and useful Improvements in Machines for MakingHead-Linings, of which the following is aspecification.

My invention relates to a machine for making head linings for barrelsand the like, the object being the production of a machine by which thinboards may be fashioned into head linings, each lining to belongitudinally curved or concavo-convex in general shape, the edgescurved or concavo-convex, and a cross section of the same rhomboidal.

The invention consists, objectively, in a machine comprising means ormechanism for intermittently feeding thin boards disposed in layersobliquely into the path of a movable knife or cutting edge; means ormechanism for holding the layers while they are being cut, or pressingthe said layers to a concaveconvex shape and holding them while beingcut; means or mechanism for operating a knife or cutting edge; and meansfor holding the linings when out in parallel layers so they mayberemoved and secured together in compact bundles.

It further consists in a machine comprising means or mechanism forreciprocating a knife or cutting edge, and means for intermittentlydelivering a layer of thin boards obliquely to the path of the movableknife.

Finally, it consists in certain novelties of construction andcombinations and arrangements of parts as hereinafter set forth andclaimed.

The accompanying drawings illustrate an example of the physicalembodiment of the invention constructed according to the best of theseveral modes I have so far devised for the practical ap lication of theprinciple.

Figure 1 is a ongitudinal vertical section through a machine embodyingmy invention. Fig. 2 is a rear elevation of the same. Fig. 3 is a frontview of the machine. Fig 4. is a side elevation of a pressure foot armwith its free end projected into a notch formed in the sides of thevertical members of the pressure foot frame. Fig. 5 shows the front ofthe machine frame with the knife frame in position thereon and theconcave cutting ledge. Fig. 6 is a rear elevation of the machine frameshowing the convex pressure foot, pressure foot frame and the concavecutting ledge. Fig. 7 is a plan view of the bracket frame with the othermechanism removed. Fig. 8 is a side elevation of the bracket frameshowing one of the bed arms or platen in position. Fig. 9 is a plan viewof the pressure cam for the pressure foot showing the relative positionof the same to the crank pin and the lifting cam for the pressure foot.Fig. 10 is a plan view showing the feed eccentric in its relativeposition to the crank pin. Fig. 11 is a section through a frame uprightshowing the ways for the knife, and the pressure foot frame, also theconcave cutting ledge fixed to the upright. Fig. 12 is a side elevationof one of the weight pressed bearings for the upper feed roller shaft.Fig. 13 is a side elevation of the rocking bearing for the upper shaft.Fig. 14 is a side view of a portion of the receiving arms, showing thefinished head lining yieldingly held in position ready for bundling.Fig. 15 is an edge view of a head lining. Fig. 16 is a side view of ahead lining showing its edge curvature form. Fig. 17 is an isometricview of a head lining. Fig. 18 is an end view of a head lining showingits beveled edges.

The frame of the machine comprises a fiat base plate 1, angle ironuprights 2 secured to the base, braces 3 for the uprights, an angularcross bar 4 connecting the top of the uprights, and an intermediateplate 5 connected to the uprights as shown and constituting the fixedcutting ledge of the machine, its top ledge or surface being curved orin the shape of a segment of a circle and also inclined. The front faceof each upright is provided with angular bars 6 forming recesses betweenthemselves and the flanges of the uprights and within which recesses orways a reciprocating pressure foot frame A, and a reciprocating knifeframe B are held and guided. (See Fig. 11.)

The pressure foot frame A comprises side members 7, which are integrallycross-connected by the top bar 8, a bottom bar 9, and the pressure foot10 with its lower surface convex or curved in shape and also inclined.This pressure foot is located a suitable distance above the concavecutting ledge.

The knife frame comprises uprights 11 and the integral bottom cross bar12. The tops of each upright are j oggled outward to let in i the knife13 flush with the rear surface of the frame, said knife being paralleland preferably in frictional contact with the pressure foot. 15 arebearings within which a main shaft 16 is journaled and provided with acrank disk 17 having a crank pin. A connecting rod 18 couples the bottomcross bar 12 of the knife frame to the crank pin. The rim of the crankdisk is provided with a cam 19 which is adapted to lift the pressurefoot frame A when it comes into contact with a roller 20 which ispivoted to the bottom cross bar 9 of the pressure foot frame; The weightof the pressure foot frame upon the roller pin may be partly relieved bya suspension spring 21 which is adjustably coupled by a bolt to the mainframe cross bar 4 and to the top cross bar 8 of the pressure foot frame.Positive downward pressure upon the pressure foot frame exerted by amechanism comprising a cam 22 fixed to the drive shaft 16, a rock shaft23 j ournaled in bearings 23 on the uprights 2, arms 24 fixed to theshaft at the ends near the upright and arranged to extend into notch 25formed in the edges of the respective sides of the pressure foot frame,an arm 26 fixed centrally of the rock shaft, and a push rod 27 arrangedto contact with said arm 26 when lifted by the cam. The push rod isslidably mounted in ways 28 formed in the bracket extension 29 of thebearing 14, and by interposing an adjustable compressible spring 30between the push bar and the rock arm 26, the pressure may be suitablyadjusted.

A bracket frame 31 having four side arms 32 is located at the rear ofthe uprights, and adjirstably connected thereto at a variable angle.This bracket frame isprovided with fixed bearings 38 which are sodisposed as to journal the lower feed shafls 33 at an an le to flex thethin boards to the curvature of the cutting le ige. Each shaft isprovided with a serrated feed roller 34, and a spur wheel 35. A top feedroller 36 is mounted to each of the respective shafts 37, which are eachjournaled in a sliding bearing 39 and a rock b waring 40, each shaftalso having a spur wheel 40 arranged to mesh with the respective spurwheel 35 on the lower shaft. The sliding bearin s are each provided witha slotted pin 4O through which is projected a lever 41. These levers 41are pivoted to the bracket frame and are each provided with a movableweight 42.

The driving mechanism for the feed rollers consists of an eccentric 43on the drive shaft 16, pitman 44, pull rod 45, having a pawl 46 arrangedto downwardly engage a ratchet wheel 47 which is fixed to a shaft 48journaled in bearings 49 and having also mounted thereon bevel gears 50which mesh with bevel gears 51 on the respective driven roller shafts33.

At the upper ends of standards 14 and able along a splined portion 52 onthe drive To permit adjustment of the eccentric feed bracket frame, theeccentric 43 is made movshaft 16, and pull rod 45 is held in a sleeve 53having an arm 54 movable in the bracket extension 54 of the bearing 15.

The thin boards are advanced to the feed rollers upon arms or bed platen55, and in the gap between the feed rollers and in front of the pressurefoot. The boards are pressed downward by a spring 56, secured toprojection 64 upon bed or platen 55 and also arms 57 extending from therear of the cutting ledge. The end of the spring is held in a notch 57formed in the pressure foot. The strips cut from the thin boards, nowfin ished head linings, are delivered between inclined arms 58 and 59which are secured to the uprights 2 of the frame by means of the hangers58. The top arm 59 is provided at the under side with a series of flatsteel springs 60 secured at their upper ends, the low er ends being freeand pressing downwards on the top of the head linings thereby holdingthem in their upright and regular positions as they are advanced downthe inclined arms. By this arrangement the head linings can readilybeplaced in bundles collectively, without the handling of each headlining separately. The fixed cutting ledge 5 is also provided withsprings 61 fixed on its face, each spring having a lip 62 adapted tobridge the knife gap betv een the cutting ledge and the low er arms 58.The spring is displaced when the knife comes dow n and returns to itsoriginal position u hen the knife passes upwardly. When the knife is atthe end of the upward stroke, the pressure foot 10 is released to permitthe feed rollers 34 and 36 to advance the boards a suitable distanceunder the knife, the distance being determined by the pitch of the teethof the ratchet heel 47. W hen the feed is completed the pressure foot islov. ered to bear upon the top of the boards, and is forcibly held inthis position by the ac tion of the pressure of the cam 22. Immediatelyfollowing the forcible bearing of the pressure foot on the top of theboards, the knife cuts down through the boards, detaching strips fromthe boards projecting free from the pressure foot. The pressure foot isforcibly held upon the top of the boards until the knife in its upwardreturn has passed above the top of the boards, thereupon the pressurefoot is released and lifted above the boards by the lifting cam 19, thefeed motion being effective during the interval when the pressure footis in the released position and the knife is disposed above the top ofthe boards. When the thin sheets of wood are held at an angle upon thisconcave cutting ledge 5 and cut, the edge curvature and the bevelededges of the head-lining (Figs. 15, 16,

18) are produced at one stroke of the clipping mechanism, the degree ofedge curvature depending upon the arc of the cutting ledge and the anglerelative to the path of the knife at which the boards are held, thebevel of the head lining being governed by the relative position of thebed arms or platen 55 which are adjustable relative to the clippingmechanism. That is to say, by increasing or decreasing the arc of thecutting ledge (without changing the angle) the edge curvature is obtained and may be varied by increasing or decreasing the are, also thisedge curvature may be somewhat increased or decreased by varying theangle at which the thin boards are held to the arc. The extent of bevelof the head lining will depend entirely upon the angle at which the thinboards of wood are held to the line of travel of the clipping mechanism.W hen the knife 13 passes dov. n, cutting off the strip portion of theboards, now completed head linings, the preceding strips are forced bythe bevel of the knife across the gap between the cutting ledge 5 andthe delivery arms 58 and 59, the bottom of the head linings during theclipping operation being supported by the lips 62 of the springs 61,which remain in contact with. and act as auxiliaries to the cuttingledge, until the bevel of the knife has passed through the boards andenters: between the springs and the cutting ledge which action forcesthe sprin s away from the cutting ledge and the delivery arms. Upon theupward movement of the knife the springs are permitted to return incontact with the face of the cutting ledge.

The thin sheets of boards are shown by Fig. 1 of the drawings in thepositions they occupy when ready for delivery by the clipping mechanism.'I hey are arranged in layers and are flat or unbent. In some cases theymay be bent or flexed to a'concavo-com vex shape before being placedupon the delivery platen, but when steamed or wet this is not necessary.The grain of the wood should extend lon itudinally of the sheet, as isobvious, and the successive layers should not overlap. Below the knifeare shown the cut linings held in layers by the springs.

From the foregoing description taken in conne tion with the drawings, itbecomes obvious that I have produced a machine which fulfils theconditions set forth as the object of rny invention.

I/Vhile I have disclosed but one example of the physical embodiment ofmy invention and one complete mode of the application of the principle,I do not limit the scope of my invention to such embodiment or mode ofapplying the principle inasmuch as the principle may be applied in othermodes. Means or mechanism may be substituted for those shown forperforming the several functions, and parts be abstracted or added ormodified,

as is obvious, without constituting substan tial departures.
